Leather bomber jackets for men were only associated with the western part of the world during the 1900s. Unlike today, they were intended to keep pilots warm and dry when they flew up into the skies during World War I and II. Made of thick insulating leather, they had high collars that wrapped around, zippers up the front with wind flaps, elasticated cuffs, and waistband. Pilots were also issued with leather gloves and caps to match. The United Kingdom was the first country to introduce the first leather bomber jacket. In 1915, the pilots from the Royal Marine Corps who were serving in Europe were the first ones to wear them; and it slowly became part of their culture, quickly becoming important outerwear staples. 

It was not long before the culture began to cross boundaries, and ideas in the world of fashion began to diffuse; other countries also began following this trend too. It was the United States who followed the British invention and designed their very own bomber jackets for military purposes. But apart from the army and navy issue clothing, bomber jackets have captured the imagination of both commercial clothing manufacturers and a large number of fashion designers who regularly include adaptations of the original designs in their new collections. High-end designers like Gucci have also provided something that the youth of this time would like, and everybody loves Gucci bomber jackets. Since they're often worn by leading celebrities and film stars, to people like you and me, you can rest assured they will never go out of fashion.
